This striking original wartime poster was produced by “No. 915 County of Warwick Squadron, Royal Air Force” in aid of the R.A.F. Benevolent fund. It features the printed signatures of the then-exiled Czech Prime Minister Dr. E. Benes and Winston Churchill, dated, in Churchill’s hand: “April 19, 1941.” Three excerpted quotations are prominently displayed, two by Churchill (“Finest Hour” and “The Few”) and one by Oliver Cromwell. The poster is exceedingly rare and in excellent condition, with the usual folds, else fine. It is here vividly preserved, floated on 4-ply museum board, in a frame of welded brass.
